Can I login with my API Token?
Pinboard gives each user an API token which they may provide to third-party applications or services in lieu of a password. Unfortunately, Pinswift cannot use the API token for authentication because it does not use the API for some functionality. The Pinboard API is fairly limited in what it allows a third party to do. In order to implement full-text search, Pinswift must login to the Pinboard website with your username and password. Your password is stored securely on the device, and is never transmitted to any server other than the Pinboard website. If Pinboard ever updates the API to include the necessary functionality, Pinswift will move to using the API token exclusively.
